I am on the verizon carrier. my software being used is 220.127.116.11
I read in a previous post that you can hook up the BB through the usb connecting it to the internet through the standard modem under phone and modem connections.
I called verizon and they say i have to purchase an additional 15 / month for the vzaccess data setup kit. I don't know what this is about. I downloaded the vzaccess as well, but it didn't have a choice for 7250 on the drop down, only the higher model. So don't even know if this will work with 7250.

this thread instructs on how to use BB as modem. Seems pretty simple, but still doesn't work.
I will try it again though.
